ETABLE, OR OTHER EDIIBLE NATURAL OR MANU- AND PROCESS SUBSTANCE OR COMPOSITION.

OF MAKING A POWDERED FRUIT, VEGE- Application :llled September 13, 1928. Serial No. 662,444.

present invention relates to a new composition of matter in the form of a powdered, yet soluble form of a fruit, vegetable or other natural edible substance and a proc ess of making a and having such 0 roduct of such materials aracteristics.

There is a great waste of certain of the natural edible substances vegetables and the like,

perfections which such as fruits, ue to slight imcause the same to be discarded or due to the spoilation of the same in transit from the place consumption and for many other In addition, there are man points of reasons.

veniences, such as ing, transporting,

of growth to the moonin the storing, re rigeratdelivering and selling of various fruits, vegetables or other compositions as well as inconveniences in the actual form of the product when served as an edible which I overcome by In addition to this,

desired substance mind is never used the total substance of a rus fruit, grape fruit because of the lack, to means for preserving and presenting substantially the composition in such the use intended as,

of the and many the like oran ,or at a I have edible substance table and divide much of the value and of the edible product in and a eat percentage of emon, orange, citor vegetable is not used my knowledge, of for use entire original, natural form as to be ca able of for example, t e skin oils therein of a lemon usually never wholly used discovered that I can take a natural such as a fruit or a' ve ethe same into such e molecular or particle'd condition that substantially the entire substance of the original product will form ture, solution, or

carriers such as nature waters,

manufactured waters or carbonated ters, or

waters or any other liq hstanding the difference in molecular weight of the two,

et due to the minute molecular state ing the colloidal condition of the these compositions in their notwit carrier, approac edible substance,

substanti ally entirety able for use in an of uses in which any used.

a substantially stable mixcom osition with certain mineral wauid carriers in which,

the substance and liquid may be rendered availinfinite variety of manner edible may be served or I have also discovered that when such a mixture of an ex tremely divided, original the present invention.

edible substance and a liquid carrier such as water, for example, was treated to drive the water off, a powdered, soluble, substantially permanent non-fermenting edible product of great concentration and value remains.

One process I have invented for producing such novel composition of matter which comprises grinding or pulping a natural edible substance such as a lemon, orange, or other citrus fruit, grape fruit or vegetable, as numbers of manufactured products, such as catsup or the like, to an exceedingly fine degree, during which I preferably mix therewith from one to two parts of a liquid temporary or even permanent carrier such as water, although the same may be reduced to the proper size in certain instances without the use of such carrier or water, or on the other hand, the carrier may be added later. If desired, I ma reinject the pulpy matter into a mixture 0 pulp and water which is in the process of being worked. There are various types of pulp digestors and mechanical apparatus which may be employed in my process for reducing the entire original, natural edible substance into a roper degree of minute, molecular or colloi al state.

Assuming that the ground pulpy matter has been mixed with a suitable carrier, such as a natural water which may be preferred on account of its chea ness, and either run through the pulp mec ianism once or rerun sufliciently until practically the entire original composition is formed into a substantially stable mixture, or a mechanical solution as it were, with a water carrier, the productmay be desirably then worked up or coarse sprayed in a suitable tank to have the effect of further atomizin", breaking up or reducin the fineness of the size of the original su stance particles to obtain the desired stability, either temporary or permanent, of the product in the carrier or solution, the value of assuring the o erator that the original e'dible substance as been sufiiciently divided for the purposes intended or desired to ap proach or assume colloidal or very fine condition.

\Vherever in the specification or claims I refer to the mixture of the powdered material and water as a substantial stable mixture, I refer to the fact that the material is reduced to such a fine state of subdivision or which resides in thereby as well comminution that, when mixed with a liquid carrier, some of it passes into solution and the insoluble particles form a permanent suspension with the liquid carrier and do not settle so as to form a sediment upon standing. lVhenever I refer to the material as being in the colloidal state, I mean that it is so finely subdivided or comminuted as to be permanently suspended in the liquid carrier and form a permanent suspension or colloidal solution therewith.

The substance, thus made, may in itself constitute a convenient commercial product easily to be collected, stored, trans orted, sold and used from sealed receptacles aving the agvantages hereinabo-ve indicated or sugeste g However, as an object of my invention, I propose to form a powdered, soluble, edible product of material of the character indicated and hence the material operated upon thus far may be passed through a heated chamber under a vacuum to drive oil the water, care being taken, however, to avoid volatilization of any of the solid or oily constituents of the edible product, such as a lemon, for example, whereupon the product left is in a powdered highly concentrated, particularly eflicient form, as above indicated, as all of the substances of the original article are retained therein, including the pulpy substance, the juices, the skin or rind and the oils thereof, and even seeds are thoroughly ground up and retained and included in the total powdered resultant product. In some cases, the seeds contain undesirable ingredients, as in the case of peach pits, and are to be rejected or eliminated. Various types of vacuum evaporation may be employed for removing the water or other fugitive carrier, leaving the product in the powdered form indicated.

The resultant powdered product is stable, non-fermentable and can be kept indefinitely in such shape. It can be shipped, stored, sold, delivered and used directly as a powder. In addition, however, it is readily soluble in water and other liquids and may be used to make various kinds of beverages such as lemonade, and the like, depending on the original edible substance used. In the process of manufacture, a sweetening substance such as sugar, saccharin or the like may be used so that a lemonade may be made for example, by merely dissolving a small quantity of the powdered concentrated material directly in a glass of water.

The invention I have made as indicated above, I believe to be of great importance since the original fruit, vegetable or other edible substance is practically usable in its entirety with practically no loss whatever as it is even possible to use the seeds of the fruit in my product and by my process. The powdered product may be easily transported, sold and handled in the channels of commerce with or without sealing against the atmosphere with no danger of fermentation or spoiling in any way whatsoever. On the other hand, the same is mixable with Water to substantially the same effect as being soluble or is soluble therein. By reason of the molecular state of the substance whether or not in some instances the same may be chemically soluble, in either event a peculiar and desirable characteristic is the readiness in which the same may be put to all uses and purposes or practically dissolved in vario'us forms of liquid carriers such as water, for example.

Wherever in the specification and claims I use the term fruit, I have used the term in its broad sense as including an vegetable product used as a food, and am not, therefore, to be restricted to a narrower use of this term.

It is apparent that within the spirit of the invention, modifications and different arrangements may be made other than as herein disclosed, and the present disclosure is illustrative merely, the invention comprehending all variations thereof.

Having thus described my invention, what I desire to secure by Letters Patent of the United States and claim is:

1. A composition of matter comprising substantially all the constituents of a natural fruit chemically unchanged and reduced to such a fine state of subdivision as to form a colloidal solution in the presence of water.
